Chondromalacia, left hip

This code signifies the degeneration of articular cartilage on the femoral head or acetabulum of the left hip joint. It represents a softening and breakdown of the cartilage, leading to pain and impaired joint function. This condition is often a precursor to osteoarthritis.

Apply this code when documentation explicitly states chondromalacia affecting the left hip. This diagnosis is typically supported by imaging findings (e.g., MRI showing cartilage changes) and clinical assessment of left hip pain and crepitus.

• Ensure laterality is clearly documented as "left hip" to avoid incorrect coding.
• Distinguish from osteoarthritis (M16.x) if there is no evidence of full-thickness cartilage loss or subchondral bone changes.
• Consider sequencing this code after a pain code (e.g., M25.552) if the pain is the primary reason for the encounter.
